Description

Technical Field

[0001] This utility model relates to the field of fan silencing technology, and in particular to a fan silencing device for a multi-unit dust collector. Background Technology

[0002] Existing fan silencers, to facilitate the replacement and cleaning of silencer components, use easily detachable components such as magnets and adsorption plates to connect the mounting plate and the silencer components. However, if one part of the silencer component malfunctions, the entire silencer component needs to be replaced or cleaned. Furthermore, the device cannot be temporarily operated while cleaning the silencer component. For example, a multi-unit dust collector fan silencer device disclosed in Chinese Patent Application No. CN202420183316.8 uses a fixed magnet inside the mounting plate to fix a connecting plate with an adsorption plate on its side surface. It also fixes the sound-absorbing plate and sound-absorbing cotton on the side of the connecting plate away from the adsorption plate. When the sound-absorbing cotton is damaged or dusty, reducing the silencer effect, it is easy to replace the damaged or dusty sound-absorbing cotton. However, when the sound-absorbing cotton is damaged or the silencer effect is reduced, the entire sound-absorbing component must be disassembled and replaced. Temporary operation is not possible during cleaning. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a silencer device for a multi-unit dust collector fan. A threaded groove is provided on the inner side wall of the outer shell, so that the sound-absorbing plate can slide along the threaded groove. The slots on the side surface of the sound-absorbing plate cooperate with the locking blocks to fix the sound-absorbing plate. Multiple sound-absorbing components are evenly distributed, so that the threaded groove and the conical sound-absorbing block are staggered, which facilitates the disassembly and assembly of the sound-absorbing components. The threaded groove can enhance the stability of the sound-absorbing plate and prevent it from shaking. The threaded groove and the conical sound-absorbing block work together to reduce turbulence and eddies, extend the sound wave propagation path, and cause the sound wave to undergo multiple reflections and scattering, thereby achieving gradual attenuation of noise energy.

[0004] This utility model also provides a multi-unit dust collector fan silencer device, comprising: a housing, an air guide pipe fixedly connected to one end of the housing, a flange fixedly connected to the end of the air guide pipe away from the housing, a threaded groove formed on the inner side wall of the housing, a rotating ring rotatably connected to the side surface of the housing, a rotating rod rotatably connected to the inner side wall of the rotating ring, and a locking block fixedly connected to the end of the rotating rod away from the rotating ring; a sound-absorbing plate, a slider fixedly connected to the side surface of the sound-absorbing plate, the side surface of the sound-absorbing plate being made of rubber, a locking groove formed on the side surface of the sound-absorbing plate, and a sound-absorbing block fixedly connected to the inner side wall of the sound-absorbing plate. The above components include threaded grooves on the inner wall of the outer casing, allowing the sound-absorbing panel to slide along these grooves. The locking slots on the side surface of the sound-absorbing panel, along with the locking blocks, secure the panel in place. Multiple sound-absorbing components are evenly distributed, with the threaded grooves and conical sound-absorbing blocks staggered for easy assembly and disassembly. The threaded grooves also enhance the stability of the sound-absorbing panel, preventing it from shaking. The combination of the threaded grooves and conical sound-absorbing blocks reduces turbulence and eddies, extends the sound wave propagation path, and causes multiple reflections and scattering of the sound waves, thereby achieving gradual attenuation of noise energy.

[0005] According to the present invention, a multi-unit dust collector fan silencer device includes two air guide pipes located at both ends of the outer casing, and several rotating rings evenly distributed on the side surface of the outer casing. These components facilitate the introduction of air into the device and allow for easy control of the fastening components of the multiple silencer parts.

[0006] According to the present invention, a multi-unit dust collector fan silencer device includes several rotating rods that are slidably connected to the interior of a housing, and a stop block is provided inside the housing. These components enable the rotating rods to move the stop block, thus restricting the sound-absorbing panel.

[0007] According to the multi-unit dust collector fan silencer device of this utility model, the side surface of the rotating rod contacts the stop block, and a spring is provided on the lower surface of the stop block. These components allow the rotating rod to be stopped by the stop block, thereby driving the locking block into the locking slot and enabling the locking block to reset.

[0008] According to the multi-unit dust collector fan silencer device of this utility model, the end of the spring away from the stop block is fixedly connected to the upper surface of the locking block side, and the inner sidewall of the locking groove is slidably connected to the locking block. These components enable the spring to reset the locking block.

[0009] According to the multi-unit dust collector fan silencer device of this utility model, the slider is slidably connected to the inner wall of the threaded groove, and the sound-absorbing block is set in a conical shape. Through these components, the sound-absorbing plate can be slidably installed inside the threaded groove, allowing the sound-absorbing block, in conjunction with the threaded groove, to extend the path of the sound wave, thus gradually attenuating the sound wave's power.

[0010] According to the present invention, a silencer device for a multi-unit dust collector fan is provided, wherein the sound-absorbing plate is located inside the outer casing and inside the rotating ring. These components allow the sound-absorbing plate to be installed inside the outer casing, and the rotating ring secures the sound-absorbing plate in place.

[0011] According to the present invention, a multi-unit dust collector fan silencer device is provided inside the outer shell, which provides a slot for the movement of a rotating ring, a rotating rod, a spring, and a locking block, so that the rotation of the rotating ring can drive the locking block to properly fasten the sound-absorbing plate.

[0012] Beneficial effects:

[0013] Compared with the prior art, this utility model has a threaded groove on the inner wall of the outer shell, which allows the sound-absorbing plate to slide along the threaded groove. The slots on the side surface of the sound-absorbing plate cooperate with the locking blocks to fix the sound-absorbing plate. Multiple sound-absorbing components are evenly distributed, and the threaded grooves and conical sound-absorbing blocks are staggered, which facilitates the disassembly and assembly of the sound-absorbing components. The threaded grooves can enhance the stability of the sound-absorbing plate and prevent it from shaking. The threaded grooves and conical sound-absorbing blocks work together to reduce turbulence and eddies, and extend the sound wave propagation path, so that the sound waves are reflected and scattered multiple times, thereby achieving gradual attenuation of noise energy.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5 This utility model discloses a silencer device for a multi-unit dust collector fan, comprising: a housing 1 that restricts airflow; a stop 12 inside the housing 1 that blocks the rotating rod 6, allowing it to move a locking block 7; two air guide pipes 2 fixedly connected to the ends of the housing 1 to guide air into the housing 1; a flange 3 fixedly connected to the end of the air guide pipe 2 away from the housing 1 for connecting the devices; threaded grooves 4 on the inner sidewall of the housing 1 for sliding installation of sound-absorbing panels 8 and for guiding airflow, preventing the formation of eddies and turbulence, extending the sound wave propagation path, and reducing noise; and rotating rings 5 ​​rotatably connected to the side surface of the housing 1 for controlling the movement of the rotating rod 6. Several rotating rings 5 ​​are evenly distributed on the side of the housing 1. On the surface, the sound-absorbing components are evenly installed. The inner wall of the rotating ring 5 is rotatably connected to the rotating rod 6, which drives the movement of the locking block 7. There are several rotating rods 6, which are slidably connected to the inside of the outer shell 1 to increase the installation stability of the sound-absorbing plate 8. The end of the rotating rod 6 away from the rotating ring 5 is fixedly connected to the locking block 7, which cooperates with the locking slot 10 to restrict the movement of the sound-absorbing plate 8. The side surface of the rotating rod 6 contacts the stop block 12, so that the rotating rod 6 can rotate around the stop block 12. A spring 13 is provided on the lower surface of the stop block 12, which realizes the reset of the locking block 7 after the locking block 7 is retracted. The end of the spring 13 away from the stop block 12 is fixedly connected to the upper surface of the locking block 7 to provide support for the spring 13. The inside of the outer shell 1 is provided with a slot for the rotating ring 5, the rotating rod 6, the spring 13 and the locking block 7 to move, so that the rotating ring 5 can normally drive the locking block 7 to insert into the locking slot 10.

[0024] The sound-absorbing plate 8 is used to fix the position of the sound-absorbing block 11. The sound-absorbing plate 8 is located inside the outer shell 1 and inside the rotating ring 5. The sound-absorbing component is installed inside the outer shell 1. A slider 9 is fixedly connected to the side surface of the sound-absorbing plate 8, which drives the sound-absorbing plate 8 to slide inside the threaded groove 4. The slider 9 is slidably connected to the inner wall of the threaded groove 4 to restrict the movement path of the sound-absorbing plate 8. The side surface of the sound-absorbing plate 8 is made of rubber to prevent air leakage from the connection between the sound-absorbing plate 8 and the outer shell 1. A slot 10 is opened on the side surface of the sound-absorbing plate 8, which works with the slot 7 to restrict the movement of the sound-absorbing plate 8. The inner wall of the slot 10 is slidably connected to the slot 7, so that the slot 7 can be properly inserted into the slot 10. The sound-absorbing block 11 is fixedly connected to the inner wall of the sound-absorbing plate 8 to absorb the noise generated by the air flow. The sound-absorbing block 11 is set in a conical shape, which works with the threaded groove 4 to reduce turbulence and eddies, and lengthen the sound wave propagation path, so that the sound wave undergoes multiple reflections and scattering, thereby achieving gradual attenuation of noise energy.

[0025] Working principle: During the use of the device, the air duct 2 is connected to the dust collector through the flange 3. The dust collector introduces air into the device and into the outer shell 1 through the air duct 2. The air is guided through the threaded groove 4 on the inner side wall of the outer shell 1. With the help of the conical sound-absorbing block 11, turbulence and eddies are reduced, the sound wave propagation path is extended, and the sound wave is reflected and scattered multiple times, thereby achieving the gradual attenuation of noise energy. Since the sound-absorbing blocks 11 are evenly distributed on the inner wall of the outer shell 1, the generation of turbulence and eddies is further reduced. When the sound-absorbing effect of a certain sound-absorbing block 11 decreases, the rotating ring 5 can be rotated to drive the rotating rod 6 to rotate. The rotating rod 6 rotates around the stop block 12, thereby driving the locking block 7 to move. This allows the locking block 7 to slide out from the inside of the locking groove 10, so that the locking block 7 no longer restricts the position of the sound-absorbing plate 8. At this time, the sound-absorbing plate 8 can be slid through the threaded groove 4 and taken out from the inside of the outer shell 1, realizing quick disassembly. This makes it easy to replace or clean the sound-absorbing blocks 11. If only some sound-absorbing blocks 11 need to be cleaned, the sound-absorbing block 11 that needs to be cleaned can be taken out and the device can be put back, so that the device can be used temporarily and prevent the cleaning process from affecting the operation of the device. After the sound-absorbing components are cleaned, the sound-absorbing plate 8 is put into the inside of the outer shell 1 through the threaded groove 4. The locking block 7 is reset by the spring 13 to fix the sound-absorbing plate 8, thus completing the quick installation of the sound-absorbing components.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
